A picture can tell you a lot about an athlete, especially how effective his technique is.
For example, look at foot touchdown in these two pictures. Both runners, plant the foot on the outside edge in a manner where the cleats cannot engage with the ground. Thus they have very little traction. If the ground was wet, they would slip! If they plant the foot in this manner in order to execute a cut to the opposite side, they would be much better off using the other leg.
In both pictures it appears that the runners have their ankles heavily taped. This in turn prohibits the ankle from turning (abducting) which would allow the whole foot to come down to get more traction with the ground. The taping may help prevent ankle sprains but it does not allow them to execute the actions needed.
In the top picture you can see how the plant leg crosses the midline of the body. In effective running and cutting actions this should never happen. It is very inefficient and leaves the player in a vulnerable position if he is hit at this time.
